All stable on my side

Herewith, current information for pool mining Gapcoin ...

The original and 'final' CPU/GPU miner release(s) for Gapcoin by j0nn9 (i.e. crt-rev5 and crt-rev5.1) were somewhat experimental, they are perhaps unstable for more modern graphics cards and require continued development.

Those binary releases are perhaps best suited for RPC / solo mining (and testing), before a new GPU miner and separate (or combined) CRT miner can be developed and released. Compiling these releases on linux from the original sources is also rather 'tricky' at present and the binaries need testing on => Ubuntu 18.04 LTS etc.,

Judging by pool difficulty and network difficulty I'm guessing all users are currently CPU mining only, this of course may change quite quickly !

...

CPU Pool mining set-up guide:

Pool: https://gap.suprnova.cc

Linux:

The optimal 'working' binary release for CPU mining in the pool is currently gapminer-rev4. I've tested this release on Ubuntu 18.04 LTS and the dependencies are met and it's very stable.

- https://github.com/gapcoin-project/GapMiner/releases

At present, I will suggest set-up as follows:

Code:

wget github.com/gapcoin/GapMiner/releases/download/gapminer-rev4/linux.zip

Code:

sudo apt-get install p7zip-full

Code:

7z x linux.zip

Running gapminer-cpu (requires pool registration and worker set-up):

Code:

linux/64/cpu/gapminer-cpu -o gap.suprnova.cc -p 2433 -u YOURusername.YOURworker -x YOURpassword --retries -1 -t 1 --stratum

N.B. Where -t is the number of CPU cores (threads) to mine with.

DONE !

IMPORTANT : Please read how to action a CPU limit of upto 75% max. before you start Mining on a cloud server! (also useful for desktop mining upto say 97-99% max. to help preserve your hardware and/or productivity!) ...

- https://bitcointalk.org/index.php?topic=822498.msg40934201#msg40934201

N.B. No requirement to run gapcoind for pool mining here of course ... however the PID your looking for instead in top is: gapminer-cpu

...

Windows Desktop:

See: https://github.com/gapcoin/GapMiner/releases/

Download: https://github.com/gapcoin/GapMiner/releases/download/gapminer-rev4/windows.zip

"GapMiner revision 4: supports CPU / GPU mining.
Changes: rewrote stratum network stuff to remove boost dependencies and to fix windows support."

Currently untested. If someone would like to confim that cpu mining on windows is still working in the pool with gapminer-rev4 that would be great!

TBH I see absolutely no reason why it wouldn't ...

Simply unpack the windows.zip , then navigate to locate gapminer-cpu.exe , move it to an appropriate folder on your drive, second mouse button click > Send to (create shortcut) to create a shortcut on your desktop (or drop and drag). Now second mouse button click the shortcut link > Properties and append to the Target: line ...

Code:

 -o gap.suprnova.cc -p 2433 -u YOURusername.YOURworker -x YOURpassword --retries -1 -t 1 --stratum

Apply and run gapminer-cpu.exe via the Shortcut.

N.B. Again, where -t is the number of CPU cores (threads) to mine with.

DONE !

N.B. or alternatively the .bat method should work just fine!

Good luck!

That does seem to be the case according to a comment in the source:

In an attempt to shed some light on the effects of using different values for the "shift" parameter, I did some data processing of Gapcoin record merits and the Gapcoin blockchain, relating merits to shifts and other data. The results are available in an OpenOffice spreadsheet (249Kb): https://mega.nz/file/OEsyVAxb#xdodexNJ9ZbyH5gTM370GCuCrzE2crZZ90lBhNulv3I if you wish to create charts similar to the following - in which merit is plotted against shift:



and raw csv format (152Kb) if preferred: https://mega.nz/file/3FsyBI6Q#F6r59XEZmhURBZ_du_8QcnFYmKNm3Sh-VsHEo_wKE4s in which the columns are: block, date, difficulty, shift, adder, gap size, merit, number of digits in the prime and the prime itself.

It's of interest because the consequence of using the default parameters unchanged is that gaps are tested for a limited range over and over again, with new records usually making only incremental improvements to existing records rather than establishing entirely new record gaps (fwiw, the record merit used a shift of 32). Changing the mining parameters changes the locus of the gap search to ranges which haven't been so intensively already mined. The chart shows the gaps in the gaps, so to speak.

The raw data for the analysis was extracted from the blockchain and formatted as SQL inserts for reading into SQLite3. The (77Mb) zipped file of SQL inserts is available at https://mega.nz/file/CI0XVaKa#AqtWAdhmTaVrOW1DSPjHWxMt6T4V0j6ETTqsfN792d0 and there is a zipped SQLite3 database file (1446Mb) ready for loading directly into the SQLite3 DB Browser available at https://mega.nz/file/XZ0zUKxZ#dPz3OBpyulEcWAkeKwMd78lDqv278jncfUubSgp2ddw

The raw data for the record gaps is available in CSV format (8.1Mb) from the Prime Gap List project's web site git repo on github - https://github.com/primegap-list-project/primegap-list-project.github.io/blob/master/_data/allgaps.csv and in SQL insert format (12.6Mb) from the project's main repos: https://github.com/primegap-list-project/prime-gap-list/blob/master/allgaps.sql

It's a beautiful thing!

I've solo mined in the 896 shift range and found it to be quite optimal, but this chart really does help to show the true mathematical potential here.

Pooled mining enabled across the shift ranges, combined with a new solid GPU / CRT miner is easily going to fill the gaps in the gaps and produce lots of new MERIT record prime gaps, protocol and PoW 'as-is'.

Certainly both the cryptocurrency community and mathematics community should begin to take notice when we actually break gapcoins own record?

I think I would hook an asic to it. With it, I will put bitcoinfx punk on his knees. He swanks being a solo guy, well good for him. Maybe your a soloist in every other aspect of your life, namely self-stimulation of ur genitals and fulfillment of other needs, but Im not that guy. I know that no one dared to put an asic on it heretofore. I will be the first humming internet guy to end this coins life cycle.

Utter nonsense. You've simply revealed your profound ignorance and exposed yourself as an offensive troll. ASIC is an acronym of "Application-specific integrated circuit", in this instance the specific application is not generating hashes but of testing for primality, an application for which no ASIC implementation exists.

N.B. sieve-primes values are unlikely to be optimal, although should increase performance above the 'default'.

Stratum's also a bit of a 'fixer upper'.

It's fine on Windows 7 32&64 bits.
It's fine on Windows 10 32&64 bits.

Anyone digging out older AMD graphics hardware for testing the GPU miner releases ?

Remember that the sieve still runs on the CPU, so 4 cores min. approx. + 8GB RAM min. recommended.

Chinese remainder theorem
- https://en.wikipedia.org/wiki/Chinese_remainder_theorem

... " Encryption

Most implementations of RSA use the Chinese remainder theorem during signing of HTTPS certificates and during decryption.

The Chinese remainder theorem can also be used in secret sharing, which consists of distributing a set of shares among a group of people who, all together (but no one alone), can recover a certain secret from the given set of shares. Each of the shares is represented in a congruence, and the solution of the system of congruences using the Chinese remainder theorem is the secret to be recovered. Secret sharing using the Chinese remainder theorem uses, along with the Chinese remainder theorem, special sequences of integers that guarantee the impossibility of recovering the secret from a set of shares with less than a certain cardinality.

Address your posts to the group, I'm not your personal tech support monkey.

/usr/bin/ld: /lib/x86_64-linux-gnu/libpthread.so.0: error adding symbols: DSO missing from command line

I don't know why you are posting this to the group, a trivial search on "DSO missing from command line" produces the result: https://stackoverflow.com/questions/24096807/dso-missing-from-command-line which leads to a variety of suggestions for fixes.

You erroneously presume that I feel obliged to provide support for arbitrary OS distros. I'll make it clear - if there's a general issue with a mainstream distro affecting a number of users then I might well be minded to help, if I can.

Can you give a little more details how the logic flow for the notary system.......thanks

Not really because I don't understand your question. Maybe these descriptions of creating an OP_RETURN transaction will help you:

2. Indicate which platform and OS version you are using.
3. Indicate the nature of the problem and any error messages that you are seeing.
